Functions

func Free

func Free(n int) (ports []int, err error)

Free returns a list of free ports from the allocated port block. It is safe to call this method concurrently. Ports have been tested to be available on 127.0.0.1 TCP but there is no guarantee that they will remain free in the future.

func Get

func Get(n int) (ports []int)

Get wraps the Free function and panics on any failure retrieving ports.

func GetT

func GetT(t testing.T, n int) (ports []int)

GetT is suitable for use when retrieving unused ports in tests. If there is an error retrieving free ports, the test will be failed.
